CANCELING DEVICE.

Application led'l'a'nuary' 13, 1923. Serial No. 612,368;

l magazines, as for example machines of the- .tlype shown in the-copending patent appli-- cation Serial No. 469,045.

These'machines may be provided with reg-- isteis for registering a row or line of characters written down by means of keys. The iegistersconsist of longitudinally movable members or bars each provided with a seriesof'7 settaib'le'- engaging devices. The settable engaging ldevices are set'by the keys with the aid'cff'actuatmg-members mounted on a' carriei: adaptedto travel from' registerto regis-- ter'- through" the' entire machine. The" can` ing a registering op deling devices for cancel eration, or for restoring a said settable'V enf gagingf device; t'o* its normal position', may Consistof another member, which for con` veniencewill be called a canceling bar adapted toltravel from register to register through the' machine' and providedv withy as many' projections or' restoringfingers or thev like a's-ther'e are actuating' members 'mounted cin thecarrier first" mentioned. The travel` ling canceling bar is preferably linked at one end to a rocker bar that extends trans"-A 40 versely through' tliemachine'and is adapted to be actuated by a canceling'key The canceling' device may also comprise,v

means for canceling the operation' of changing devices which are operated to change the normalrelation between the type registersl or type-position-determining-devicesand the' typeb'ar'` moving' members, and

ic'tween the magazine registers or magazine-l position-determiningdevices` and magazine 0 moving members.

A further' feature of the invention consiste in means for ensuring the proper cancellation of individual registering opera-tions and the common restoration of all settable registering members after they have fulfilled their functions. consists of members which prevent the longitudinally movable members that carry the settable engaging devices from being shifted in the one direction of their travel when they have been moved out of their initial positions. The manner in which this isaecomplished and further details of the invention will appear more fully hereinafter and in the claims and drawings.

This ensuring means Fig. l is a vertical section on a line'eX- tending'from the front tothe back of a typebar printing machine provided with canceling devices'` for canceling the operation of individual type-positioii-determining-mem bers, changing devices for changing the relation' between the registers and the typemovingmembers, and for canceling all operated magazine-position and type-positiondetermining members simultaneously.

Fig. 2 isa side view of details of the' canceling devices for canceling the operations of individual type-position-determining-membersand of a changing device.

Fig'. 3 is a side View and partialsectional" vievvy of the-canceling device' by which all of the` type-position'-determining membersare restored together.

Referring to the drawing b isa rod which is: capable? of being reciprocated and provided with projections lor strikers c1, c2, o3. The striker c3 is indicated by dotted lines in a position which it occupies when the rod` bl is moved inwards. A tilting bar Z1 which extends transversely through the machine, isalso' shown in broken lines in the position into which it is tilted by the dotted striker 031 g1 isl a bar or carrier adapted to be moved transversely through thet machine from one magazine register to another, the magazineA registers each consisting of a :slotted plate h1 with pivoted tappets 0r engaging members f1 mounted thereon. The transversely movable carrier g1 is provided with an actuating member e1 for each engaging member as f1. Also mounted on the, transversely movablecarrier g1 is a cancel-l ing device consisting of a bar Q1' arranged to slide longitudinally on thel carrier g1 and provided with a number of upwardly projectiiig restoring ngers g2, g3. Theleft hand end of the canceling device Q1 is coupled withy a rocker bar g4 lwhich extends transversely through the machine and is adapted to be rocked by a key g5. When the ioo rocker bar Qt is rocked by depressing the key g5 the canceling bar g1 is made to slide to the lett as indicated by the arrow in Fig.

2 Vso that a restoring finger g2 will restore the operated engaging member f1 to its initial position.

Thus it will be seen that it a wrong magazine positiondetermining member or engaging member, as f1, is operated,the car-- rier g1 which travels transversely through the machine may be moved back one step in the manner well known in writing machines and then the operation of the wrongly actuated engaging member f1 can be canceled, i. e., this member can be restored to its normal position, by depressing the canceling key g5.

The magazine registers are each coupled to a magazine lifting device that consists ot a bar nl and a lever` o1 which, when the bar nl is pulled in the direction of the 'arrow 2 is adapted to lift a typebar magazine A changing device consisting ot an actuating member e3, a coupling member y', and

teeth at the free end of a bar Z1 is provided for changing the mechanical relation between each magazine register .and magazine lifter.` When a rod Zi is shifted so as to cause its striker c1 to tilt the tilting bar CZ: the actuating member e3 is swung upwards so as to engage the left hand end ot the coupling member 7' and to cause the hook 7"- of this member to swing downwards. A

`s rin(T or the' like immediatel swinvsthe hook ,7'1 upwards again causing it to engage with the second tooth on the bar nl as indicated in Fig. 2. This operation of the changing device can be cancelled by causing the restoring finger (g3 to move to the left and to carry the projection n and the arm nl towards the left so as to cause the hook .7'1 to slip back into engagement with the second or inner tooth on the link 'al as shown in Fig. l. The leftward movement of the restoring finger g3 is also effected by depresing the canceling key g5 and thus causing the canceling bar g3 to slide to the left.

The machine is also provided with typebar registers h2 and changing devices e4 each of which latter consists of members like et, i2 and teeth on the typebar Shifters n2 and which serve to change the relation between the registers Zz? and the typebar shifters n2.V The top parts of the typebar shifter-s n2 arel adapt-ed to enter the magazines r and to push the typebars c contained therein out into theprinting position.

\ It will be obvious that the individual can celing devices for canceling the operation ot individual typebar position determining members or typebar registers 7i?, and for canceling the operation of the changing devices which connect the typebar registers to the typebar engaging members f2 on the Shifters n2, may be similar tothe canceling devices already described above.

The means for simultaneously canceling or restoring' a row or series of operated en* gaging members on diiierent registers consist oi common restoring bars, one bar Z3 for the magazine register and another bar ZL for the typebar registers. These restoring bars are adapted to be coupled to the bars Zl and Z2 by means of the dogs Z5 and Z6` respectively when these bars Z1, Z2 are shifted in the direction of the arrows 2 for the purpose o' cooperating with operated engaging members f1, f2 on the registers so as to raise the magazines r and to push out the typebars ci into the positions previously determined by the setting of the engaging members on the registers by means of the depressible keys of the machine.

The tree endot the dog Z5, which, on ac count of its own weight or of a downwardly pressing spriifig, tends to swing downward, has a laterally projectingpin or the like which is adapted` to slide irst on the upwardly inclined surface of a slidewa-y ZT and then on the downwardly inclined surface of th slider in Thus, when the magazine i bar t i y p will `be lifted storing bar Z3 clear of the common reand will then be lower again with its hook in the path of the bar Z3. On the magazine operating bar Z1` being thereupon moved bak to the right the hook of the dog Z5 will seize the restoring bar Z3 and carry it towards the rightwhile the registers Ziilwith their operated engaging mem. bers f1 will ren'lain in theirfoperatedposit-ions until the restoring bar Z3 reaches the operated engaging members and swings them all down into their normal positions.l The upwardly projectingl portions of the engaging members 7"]- are, or course, shaped so as to, enable them to move out from between the bars Z3 and Z1. On themovement ofthe bar Z1,.with the connected bar Z3 andthe dog Z5, being continued towards the right, the laterally projecting pin on the'free end of the dog Z will slide upon the left hand inf clined surface ot the slide way Z7 and the dog Z5 will thus be unhooke'd4 from the restoring bar Z3. The coupling between the restoring bar Z3 and the magazine operating bar ZiV is thus disengaged. The register Ztl 1s pre-` vented from moving during this restoring operation by means of a ratchet iormed on the top of theregister and a pawl mi. After,

shifted tothe right, thev of' the ratchets on the registers. Vhenthe magazine operating bar' Z1' was moved :torward' to tlie left it tilted the pawl-operatmg member m1 clockwise' and thus caused it to permit the pawl m3 to drop into engagement with the register ratchets as indicated iny Fig. 3.

Similar common restoring devices to those which have been described for the magazine registerscam-of course, also be used in connection with the typebar registers.

The simultaneous restoration of the registers could also be accomplished by a ixed common' restoring bar Z3 if the registers h1 or/iZ were arranged to execute a shortmovement to the left after the typebars have been moved into the printing position. This short' leftward motion couldl be produced by shifting the! bar or pawl m3 to the left so as to causev the upwardly extending portionsofrthe actuating' members fl to strike against'the fixed common restoring bar Z3.

The:l same results ycould be obtained it' theV registers 71,1, h2 were first returned to normal and the common restoring bar Z were then moved.' towards` the right.
